alsa_sound: Add support for sound card in Galaxy S4 Mini

alsa_sound: Improve USB device detection

 * Samsung's proprietary dock was hijacking the routing when a USB audio
   device such as a DAC was connected in host mode.
 * Instead of blindly shoving stuff down a route that doesn't work for
   the dock case, check the switch in sysfs for the proprietary dock
   first.
 * Remove the DOCK_USBAUDIO define entirely and just wrap it up with
   everything else that SAMSUNG_AUDIO includes.

msm8660: suppress some logcat spam.

There is a lot of logcat spamming going on by this. Moved some logs down
a level to ALOGV, and some of the AudioHardware.xxxx.(standby) commented
out completely.

Reverting this small change fixes an issue where the mic does not work
in anything else but dialer/phone. GNow etc all crash. This small change
fixes that.

This reverts commit c3a461aabec762307d77dd18db11593e96885cd7.

alsa_sound: Fix to Support in-call uplink recording

Uplink recording during voice call fails as the case was not
 getting handled while opening the input stream.
 -Added support for Incall Uplink recording in openInputStream.

GTalk call doesn't work if call is started during an existing
 recording session. All subsequent calls are failing after this
 scenario
 - Move the pcm device node open to read() call instead which will
   avoid opening the pcm device node of normal recording session
   and doesn't go into the error state. This will allow GTalk call
   to work and also all the subsequent calls to work

alsa_sound :Starting "UsbRecordingThread" if not started

- Recorder stop() was getting called in hangout app before the
  call got connected, this will stop UsbRecordingThread.
  Recorder set() is called with a sample rate of 48k due to which
  the USB recording thread doesnt get re-started because for VOIP
  the sample rate expected is 8/16k.

- UsbRecordingThread has to get started when the call
  gets connected.
